TECHNICAL FIELD

The present disclosure relates to the field of safety devices, and, more particularly, to a school bus safety device and related methods.

BACKGROUND

Given the primary purpose of a school bus vehicle, these vehicles include several safety devices. Indeed, governmental regulation, both federal and state level, require certain features. In particular, the Federal Motor Vehicle Safety Standards (FMVSS) for School Buses requires school bus pedestrian safety devices, for example, a stop signal arm, roll over protection, body joint strength, and passenger seating and crash protection. Of course, the federal and state regulations merely establish a floor requirement for safety devices, and there is a robust market for supplemental safety devices, such as the near ubiquitous school bus crossing arm.

Federal regulations define the “[s]top signal arm means [as] a device that can be extended outward from the side of a school bus to provide a signal to other motorists not to pass the bus because it has stopped to load or discharge passengers.” 49 C.F.R. § 571.131. Regulations mandate the shape and font lettering size for the stop signal arm. Nevertheless, there have been several approaches to improving the visibility of the stop signal arm.

For example, U.S. Pat. No. 9,245,465 to Geyer et al. discloses another approach to the stop signal arm device. This device extends further into the adjacent lane to reduce instances in which motorists pass a stopped school bus. A first frame is permanently secured to conventional stop sign mechanism. A second breakaway frame or arm is attachable to and detachable from the first frame, and extends beyond the conventional stop sign. If a vehicle strikes the second frame, it separates without significantly damaging the conventional stop sign mechanism. The extension arm can be moved between a retracted and extended position by the same mechanism that opens and closes the conventional stop sign, or with a new mechanism entirely.

SUMMARY

Generally, a safety sign device for a vehicle comprises a first sign having proximal and distal ends, and a first hinge being coupled to the proximal end of the first sign, the first hinge being coupled to a side of the vehicle. The safety sign device includes a second hinge being coupled to the distal end of the first sign, a second sign having a medial portion coupled to the second hinge, and an arm coupled between the second sign and the side of the vehicle and configured to extend and retract the first and second signs between a retracted position and an extended position. The first and second signs are transverse to each other in the extended position, and are flat against the side of the vehicle in the retracted position. The safety sign device further comprises a first flexible arm coupled to the first sign and comprising an elongate housing, and a plurality of visual indicators carried by the elongate housing, the first flexible arm being substantially parallel to the first sign. Helpfully, the flexible arm enhances visibility, and readily flexes to impact from errant vehicles.

In particular, the first flexible arm may comprise an elastic base coupled between the elongate housing and the first sign. For example, the elastic base may comprise a spring. The plurality of visual indicators may be configured to be activated when the first and second signs are in the extended position. In some embodiments, the elongate housing may comprise opposing first and second longitudinal sides, and the plurality of visual indicators may be carried on both of the opposing first and second longitudinal sides.

Additionally, the plurality of visual indicators may comprise a plurality of light emitting diodes (LEDs). The safety sign device may also include a motor coupled to the arm and configured to toggle the first and second signs between the extended and retracted positions.

In other embodiments, the safety sign device may further comprise a third sign having proximal and distal ends, and a third hinge being coupled to the proximal end of the third sign, the third hinge being coupled to the side of the vehicle spaced apart from the first hinge. The safety sign device may also comprise a second flexible arm coupled to the distal end of the third sign and comprising an elongate housing, and a plurality of visual indicators carried by the elongate housing, the second flexible arm being substantially parallel to the third sign.

Another aspect is directed to a method for making a safety sign device for a vehicle. The method includes coupling a first hinge to a proximal end of a first sign, the first hinge being coupled to a side of the vehicle, coupling a second hinge to a distal end of the first sign, and coupling a medial portion of a second sign to the second hinge. The method also includes coupling an arm between the second sign and the side of the vehicle, the arm configured to extend and retract the first and second signs between a retracted position and an extended position. The first and second signs are transverse to each other in the extended position, and are flat against the side of the vehicle in the retracted position. The method comprises coupling a first flexible arm to the first sign and comprising an elongate housing, and a plurality of visual indicators carried by the elongate housing, the first flexible arm being substantially parallel to the first sign.

DETAILED DESCRIPTION

The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which several embodiments of the invention are shown. This present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Like numbers refer to like elements throughout.

Referring initially to FIGS. 1-4, a safety sign device 10 according to the present disclosure is now described. The safety sign device 10 is illustratively attached to a vehicle 11. The vehicle 11 may comprise, for example, a school bus (providing a stop signal device), or a truck. The safety sign device 10 illustratively includes a first sign (e.g. a stop sign) 12 having proximal (i.e. closer to the vehicle) and distal (i.e. further from the vehicle) ends, and a first hinge 19 being coupled to the proximal end of the first sign. The first hinge 19 is also coupled to a side of the vehicle 11.

The safety sign device 10 illustratively includes a second hinge 20 being coupled to the distal end of the first sign 12, and a second sign (e.g. a stop sign) 13 having a medial portion coupled to the second hinge, thereby providing a dual hinged/dual signed safety sign device. The first and second hinges 19, 20 are coupled at opposite sides of the first sign 12. The safety sign device 10 illustratively includes an arm 17 coupled between the second sign 13 and the side of the vehicle 11 and configured to extend and retract the first and second signs 12-13 between a retracted position (FIG. 3) and an extended position (FIG. 2).

As will be appreciated, in the school bus application, the first and second signs 12-13 would be in the extended position when stopped and transferring passengers. The first and second signs 12-13 are transverse to each other in the extended position. In particular, the first and second signs 12-13 are substantially perpendicular to each other in the extended position, i.e. between 75-105 degrees.

Also, the first and second signs 12-13 are flat against the side of the vehicle 11 in the retracted position. As will be appreciated, in the school bus application, the first and second signs 12-13 would be in the retracted position when the vehicle 11 is in motion. In other words, the first and second signs 12-13 are substantially parallel to each other in the retracted position, i.e. within 20 degrees of parallel to each other.

The safety sign device 10 further illustratively includes a first flexible arm 14 coupled to the first sign 12 and comprising an elongate housing 16, and a plurality of visual indicators 21 a-211 carried by the elongate housing. In some embodiments, the plurality of visual indicators 21 a-211 comprises text based indicators, such as “stop”, “slow”, “caution”, which may be selectively activated via embedded light sources.

The first flexible arm 14 is substantially parallel to the first sign 12. In particular, in a rest/non-flexed state, the first flexible arm 14 is within 20 degrees of parallel to the first sign 12. Helpfully, the first flexible arm 14 enhances visibility, and readily flexes to impact from errant vehicles.

In particular, the first flexible arm 14 illustratively includes an elastic base 15 coupled between the elongate housing 16 and the first sign 12. For example, the elastic base 15 may comprise a plurality of springs, a double barreled hinge, or a 180 degree swivel hinge. In some embodiments, the elastic base 15 includes a plurality of aligned heavy duty springs. In other embodiments, the elastic base 15 may comprise a flexible polymer base having a H-shape. For example, the elastic base 15 may be constituted similarly to the lower portion of the traffic beacon disclosed in U.S. Pat. No. 7,938,594 to Schindler, the entire contents of which are hereby incorporated by reference.

In fact, due to the elastic base 15, if the first flexible arm 14 is impacted during an accident, the elongate housing 16 will readily bend away and return to its original position. Helpfully, the first flexible arm 14 is resistant to damage and inflicts little damage on the other vehicle. This is contrast to the breakaway approach of U.S. Pat. No. 9,245,465 to Geyer et al., which is costly to repair. Moreover, the light weight approach of the safety sign device 10 is readily retrofitted onto existing stop signal devices.

Also, the first flexible arm 14 has lower position close to the ground, than the approach of the '465 patent, which makes it more difficult for errant vehicles to drive under the warning arm. The first flexible arm 14 also extends longitudinally further out than the approach of the '465 patent, which enhances visibility.

In another embodiment, the elongate housing 16 of the first flexible arm 14 may comprise a rubberized external layer (other materials could be used, e.g., foam plastic). Helpfully, this rubberized external layer prevents damage to errant vehicles. Also, the external layer prevents inadvertent damage to a paint layer of the side of the vehicle 11.

The plurality of visual indicators 21 a-211 is configured to be activated when the first and second signs 12-13 are in the extended position. In some embodiments, the elongate housing 16 comprises opposing first and second longitudinal sides, and the plurality of visual indicators 21 a-211 is to be carried on both of the opposing first and second longitudinal sides. Additionally, the plurality of visual indicators 21 a-211 may comprise a plurality of LEDs.

In some embodiments, the elongate housing 16 may comprise an anti-ballistic plastic material. In other embodiments, the elongate housing 16 may comprise a metallic material or cellulose material (e.g. wood material).

In the illustrated embodiment, the safety sign device 10 further illustratively includes a fourth hinge 24, and first and second supports 22-23 coupled between the fourth hinge and the first sign 12. The first flexible arm 14 is coupled to a medial joint of the first and second supports 22-23. In other embodiments, the first flexible arm 14 may be coupled directly to the first sign 12, thereby eliminating the first and second supports 22-23.

The safety sign device 10 illustratively includes a motor 18 coupled to the arm 17 and configured to toggle the first and second signs 12-13 between the extended and retracted positions. In some embodiments, the motor 18 may be alternatively coupled to the first hinge 19 for extending the first sign 12. Advantageously, via the action of the arm 17 and the second hinge 20, the second sign 13 rotates outward into the transverse position.

Referring now additionally to FIG. 5, the safety sign device 10 illustratively includes a third sign 25 having proximal and distal ends, and a third hinge 29 being coupled to the proximal end of the third sign. The third hinge 29 is coupled to the side of the vehicle 11 spaced apart from the first hinge 19 and adjacent a rear of the vehicle. The safety sign device 10 illustratively includes a second flexible arm 30 coupled to the distal end of the third sign 25. The second flexible arm 30 illustratively includes an elastic base 26 coupled to the distal end of the third sign 25, an elongate housing 27 coupled to the elastic base, and a plurality of visual indicators 31 a-31 d carried by the elongate housing.

The safety sign device 10 illustratively includes an additional motor 28, and a third hinge 29 powered by the motor to switch between retracted and extended (FIG. 5) positions. In the extended position, the second flexible arm 30 is substantially parallel to the third sign 25. In particular, in a rest/non-flexed state, the second flexible arm 30 is within 20 degrees of parallel to the third sign 25. In the retracted position, the third sign 25 and the second flexible arm 30 are flat against the side of the vehicle 11. In other words, the third sign 25 is substantially parallel to the side of vehicle 11, i.e. within 20 degrees of parallel to each other.

In some embodiments, the motors 18, 28 may be onboard motors provided by the vehicle 11. In other embodiment, the motors 18, 28 be modular and separate from the original vehicle, i.e. aftermarket.

In yet another embodiment (FIG. 6), the safety sign device 10 illustratively includes a retention device 32 coupled to the side of the vehicle 11. The retention device 32 is configured to retain the first flexible arm 14 firmly and securely against the side of the vehicle 11 while in the retracted position. Advantageously, this feature also prevents inadvertent damage to the paint layer of the side of the vehicle 11 from movement during motion of the vehicle. The retention device 32 may comprise a flexible retention arm with a medial bump 33 configured to require the first flexible arm 14 to flex upward and out (see dashed line in FIG. 6) when being moved out of the retracted position. The retention device 32 also includes a proximal portion 34 extending outward from the side of the vehicle 11. In other embodiments, the retention device 32 may comprise an interface lock, a magnetic lock, or a spring loaded locking mechanism.

In another embodiment, the safety sign device 10 illustratively includes an image sensor device, and associated memory/processing circuitry coupled thereto. In this embodiment, the safety sign device 10 also includes a sensor configured to detect when the first flexible arm 14 is flexed beyond a threshold limit while in the extended position, for example, greater than 20 degrees from rest position (threshold degree could be between 10-45 degrees). When the sensor is triggered, the image sensor device would record the area adjacent and underneath the first flexible arm 14 for record keeping purposes.

Another aspect is directed to a method for making a safety sign device 10 for a vehicle 11. The method includes coupling a first hinge 19 to a proximal end of a first sign 12, the first hinge being coupled to a side of the vehicle 11, coupling a second hinge 20 to a distal end of the first sign, and coupling a medial portion of a second sign 13 to the second hinge. The method also includes coupling an arm 17 between the second sign 13 and the side of the vehicle 11, the arm configured to extend and retract the first and second signs 12-13 between a retracted position and an extended position. The first and second signs 12-13 are transverse to each other in the extended position, and are flat against the side of the vehicle 11 in the retracted position. The method comprises coupling a first flexible arm 14 to the first sign 12 and comprising an elongate housing 16, and a plurality of visual indicators 21 a-211 carried by the elongate housing, the first flexible arm being substantially parallel to the first sign.
